Abstract

La presente invencion se relaciona con un método que pertenece a los filtros de presion de la clase que incluye una pluralidad de platos de prensa que pueden llevarse hacia y en contacto a tope mutuo y pares de los cuales forman entre ellos por lo menos una cámara de presion, en el que se forma en cada cámara de presion, a medida que la suspension acuosa de partículas solidas es deshidratada, una torta de filtro en la cual al término del proceso de deshidratacion, es liberada de la cámara separando los platos de prensa de tal manera que la cámara se vaciará por sí misma de sus contenidos. El método está caracterizado porque el vaciado de las cámaras de presion se logra permitiendo que cada plato de prensa gire libremente y oscile alrededor de un eje, el cual se extiende por lo general horizontalmente a través del plano del plato, bajo la influencia de la torta de filtro liberada. El filtro de presion se construye de tal manera que cada plato de presion es capaz de pivotear en relacion con los carriles. Los dispositivos de traccion por medio de los cuales los platos de prensa se separan, están unidos a solo un dispositivo de acoplamiento individual sobre cada lado de cada plato de prensa, este dispositivo de acoplamiento se coloca sobre o en la cercanía inmediata del medio de rodillo de rodadura, en otras palabras en la proximidad del carril horizontal.The present invention relates to a method belonging to the pressure filters of the class that includes a plurality of press plates that can be brought towards and in contact with each other and pairs of which form at least one chamber of pressure, in which in each pressure chamber, as the aqueous suspension of solid particles is dehydrated, a filter cake in which, at the end of the dehydration process, is released from the chamber, separating the press plates from in such a way that the camera will empty itself of its contents. The method is characterized in that the emptying of the pressure chambers is achieved by allowing each press plate to rotate freely and oscillate about an axis, which generally extends horizontally across the plane of the plate, under the influence of the cake. filter released. The pressure filter is constructed in such a way that each pressure plate is capable of pivoting relative to the rails. The traction devices by means of which the press plates are separated, are attached to only one individual coupling device on each side of each press plate, this coupling device is placed on or in the immediate vicinity of the roller means rolling, in other words in the proximity of the horizontal rail.
